CONVEYER.

SPECIFICATION forming part of Letters Patent No. 712,335, dated October28, 1902.

Application filed June 20, 1902. Serial No. 112,531. (No model.)

This invention relates to a conveyer; and;

the primary object of the invention is toV provide simple and efficientmeans for counter-` balancing the reciprocatory feed member or hoe-barof such an apparatus, so that the same may run smoothly and uniformlythroughout the complete motion thereof, and the counterbalancing meansis so situated that it is not reciprocated by the feed member and ispreferably placed below the same andis connected thereto by means ofa'link or links, so as to secure the desired effect. In other words, thecounterbalancing device is supported independently of the feed member,but isoperatively connected therewith.'

While I do not limit the use of the invention to incorporation in anyparticular kind of conveyer, still for the purpose of indicating thenature of the same I have shown it embodied in a conveyer of the kinddisclosed by Letters Patent No.696,273, granted to me March 25, 1902, towhich reference may be had.

The invention will be set forth in detail in the following description,while the novelty thereof will constitute the basis of the claimssucceeding such description; and said invention is clearly illustratedin the accompanying drawings, forming a part of this specilication, andin which- Figure 1 is a side elevation of aA conveyer including myimprovements. Fig. 2 is a plan View of the same. Fig. 3 is across-sectional elevation.

Like characters refer to like parts in all the figures of the drawings.

Referring to the drawings, the numeral 12 indicates a trough sustainedat suitable intervals by standards or brackets 13, two of the latterbeing shown, although of course The trough 12, which is fixed, may be ofany suitable length and is adapted to receive the material which is tobe carried from one place to another. The

material can be delivered to the trough at any suitable point and isdischarged from one end thereof, the trough bein g of channel form.

A bar is shown at 14, and itis shown as bcing T-shaped in cross-section,it constituting the body of a feed member and being provided with aseries of' substantially equidistantly disposed depending hoes 15. Thehoes 15 consist of complemental flat plates set at right angles to theYbar 11i and having flanges along their inner edges. These flanges ofthe plates are riveted or otherwise suitably secured together for aportion of their height, and they are slightly separated near theirupper ends to fit against the opposite faces of the vertical flange ofthe T-shaped bar 14.`

Bolts passing through the lianges of the plates and bar, respectively,or other fastening means may be provided to secure the plates to thebar. The bar'll, which is disposed substantially centrally `between thesides of the trough 12, is of a less length than the said trough and isgiven, by suitable mechanism hereinafter more particularly described, areciprocatory motion through a substantiallyelliptical path, so that thedepending hoes thereon are adapted to force the material in the trougheither to the right or to the left, in accordance with the direction ofthe initial movement of said bar.

A power-shaft is shown at 17 extending across the trough at one endthereof and supported by suitable bearings and provided at one end witha suitable driving member, as the pulley 18, connected by belting with asuitable motor. (Not shown.) This shaft 17 also carries a pinion 19,meshing with the peripheral teeth of the gear or disk 20, fastened on asuitably-supported cross-shaft 21. This shaft 21 carries at one end thedisk or gear 2O and is provided at its opposite'end with a fixed disk22. To the outer faces of the disks 20 and 22 are pivoted, by means ofcran k-pins, the pitmen or connecting-rods 23 and 24,1ocated at oppositesides of the trough and extending forward in transverse alinep IOO lings shown as located a short distance to the left of their forward endsto rotatively receive the ends of another transverse shaft 26, whichsupports at its middle the bracket 27, suitably fastened to the upperside of the body or bar 14. At a point in advance of the bracket 27 is asimilar bracket 27, which is adapted to receive the shaft 26 in a mannerjust like the shaft 26, and to the ends of said shaft 26 are freelyconnected the upper arms of alined angle-levers 28, the elbows of theangle-levers, which levers, it will be seen, are arranged in alinedpairs, being adapted to receive the ends of the shaft 29.

lVhat is shown as the inner ends of the connecting-rods 23 and 24 areprovided with downwardly-disposed right angular eXtensions or arms 30,and to the lower ends of said arms are pivoted the con necting-rods 3l,said connecting-rods being likewise united to the lower arm of theangle-levers 28. The

4connecting-rods 3l, which, it will be evident,

are located at the outer sides of the trough, are divided into sectionsconnected, respectively, with the several angle-levers and the angularextensions of the connecting-rods or pitmen 23 and 24 and in turn areunited by right and left handed nuts or turnbuckles in order to securelongitudinal adjustment of the respective connecting-rods. The ends ofthe shafts 25 and 29 are rotatively supported by the upper ends of therockers 32, sustained for oscillation by the shafts 33, carried bysuitable boxes on the standards or brackets 13, which, it will beremembered, sustain the trough.

With the exception of the hoes the mechanism hereinbefore described issubstantially like that illustrated in Letters Patent previouslymentioned, and it will be evident that by rotating the primary shaft 17the feed member or hoe-bar 14 will be reciprocated in a substantiallyelliptical path, so as to push the material in the trough 12 either tothe right or to the left, in accordance with the direction thereciprocatory feed member moves on its initial operation.

In connection with the reciprocatory feed member I providecounterbalancing means which insure the even and smooth operation ofsaid feed member at all times, and the counterbalancing means is notsustained by the feed member, so that it does not reciprocate therewith,and for the sake of economyin space I prefer to support thecounterbalancing means below the feed member; but I do not desire torestrict the invention in this respect, and the counterbalancing meansnow to be described is simple and effective.

The levers 35 are fulcrumed at suitable points in theirlength to theshafts 33,to which, it will be remembered, the rockers 32 are united,and what is shown as the right ends of the levers carry weights 36,adjustable thereon in order to regulate their counterbalancing effectsand held in fixed positions by set-screws 37. The left ends of thelevers freely receive the shafts 38, to the opposite ends of which thelinks 39 are pivoted, the upper ends of said links being likewise unitedto the shafts 26 and 26. It will be understood, of course,l that thelevers may be otherwise mounted, though the number of parts is reducedby fulcruming them to the shafts 33, and in like manner they may beotherwise connected to the feed-bar 14, and while two of thecounterbalancing-levers are shown this number may ot' course be varied,and one of them, if desired, may be omitted,althougl1 I prefer to employthe arrangement illustrated. As the feed-bar rises during its ellipticalreciprocatory motion the weights 36 of course are lowered, and naturallythe reverse operation takes place on the lowering of the said feed-bar.

The invention may of course be variously modified within the scope ofthe accompanying claims, for it will be evident that my inventioncomprehends,broadly,a feed member mounted for movement in an elongatedorbital path and counterbalancing means for the conveyer supportedindependently of and operatively connected to said conveyer.

Having described the invention, what I claim is- 1. The combination ofan orbitally-movable feed member, and a counterbalancing devicesupported independently of the feed member and operatively connectedthereto.

2. The combination of an orbitally-movable feed member, and a weightedlever supported independently of the feed member, and operativelyconnected thereto.

et. rlhe combination of an orbitally-movable feed member, and acounterweighted lever supportedindependently of the feed member, and alink connection between said parts.

5. The combination with a feed member, rockers for supporting the feedmember, means for reciprocating the feed member in the orbital path, ashaft for pivotally receiving said rockers, a lever fulcrumed upon saidshaft and carrying a weight and a link connection between the lever andfeed member.

6. The combination of a feed member, a pair of rockers, a shaft forcarrying the rockers, a shaft supported by the rockers, angleleversconnected with said last-mentioned shaft at their elbows, and alsoconnected with the feed member, pitmen connected with the feed memberand having angular eXtensions, a connection between an angular extensionand one of the said angle-levers, a shaft carried by saidconnecting-rods, rockers supported by said last-mentioned shafts, a
